Model Description

■ 8429 (successor 8730) BK Connect Shock Response Analysis This BK Connect application calculates the shock response spectrum (SRS) for the test target from the transient phenomenon in the time region, such as pyroclimation and structural impact. This allows you to identify the potential damage caused by transient phenomena and predict whether the structure can withstand such a shock. In the SRS calculation, the motion input is converted to an oscillator response, including the attenuation of one flexibility (SDOF). The oscillator's response amplitude is plotted as a function of SDOF frequency and generates SRS. SRS is calculated according to the ISO 18431-4: 2007 standard for shock response analysis. ■ Characteristics This software contains the prettension of the impact phenomenon. You can check the input data before selecting the individual impact phenomenon to be analyzed. Before calculating the shock response spectrum, these individual impact phenomena can be corrected to the DC offset and drift. If necessary, the end of the input ends can be forcibly zero. Users can use 45 different options, including five types of shock response spectrum models and nine types of amplitude calculation (impact instance). ■ Functional ・ ISO 18431-4: 2007 Machine Vibration and Shock -Signal Processing -Part 4: Significance of the Shock Response Spectral Analysis ・ Shock response spectrum model: Absolute acceleration, equivalent acceleration, pseudo speed, relative speed, relative displacement ・ Import transitional acceleration, speed, and displacement. Speed ​​data and displacement data are automatically converted to acceleration data before SRS calculation. ・ In the measurement of the pyro shock, a lamp -inverarant Z conversion is performed to reduce errors at high frequencies. ・ Dynamic over sampling reduces bias errors and improves peak detection accuracy. ・ There are other functions.
